Description
Technical field
The utility model relates to a kind of material cooling device of prepared in laboratory converted starch, and this device has triple refrigerating functions, the quick cooling of material in the time of can being implemented in experiment indoor 100 L and following reactor thereof and preparing converted starch.The material that cools off can be starch, also can be unclassified stores.
Background technology
In recent years, research and the production application of converted starch have had significant progress in China, and the kind of converted starch and preparation method, preparation technology and manufacturing equipment are also in continuous increase.Converted starch has been widely used in numerous areas such as food, feed, weaving, papermaking, casting, medicine, building, oil drilling, household chemicals, biodegradation material.
At present, the production of converted starch is mainly based on wet processing, and its advantage is can fully mix between the material, constant product quality, the easy control of production process etc.The reaction temperature of wet production converted starch all can be carried out under higher temperature usually, just can carry out next step processing after will being cooled to room temperature usually after reaction finishes.Because reaction temperature directly influences chemical reaction rate and chemical balance, therefore, in the preparation process of converted starch, realize the quick cooling of material, be conducive to control the denaturation degrees of starch, realize uniformity and the stability of product quality.The laboratory type of cooling commonly used is generally nature cooling, water-bath cooling and ice-water bath cooling.Yet, when the laboratory utilizes reactor to produce converted starch, because material is many, just cause its cooling velocity slow, denaturation degrees is not easy to control, problems such as product stability and poor repeatability.Simultaneously, because cooling velocity is slow, cool time is longer, is for further processing to wait for the long period, seriously reduces operating efficiency, and therefore designing a kind of cooling device quickly and easily seems particularly urgent.
Summary of the invention
The purpose of this utility model is just at existing weak point in the above-mentioned prior art, and design a kind of cools off the material cooling device that prepared in laboratory converted starch rapid, simple in structure, easy and simple to handle, with low cost is used.
The purpose of this utility model is achieved by the following technical solution: a kind of three heavy material cooling devices of prepared in laboratory converted starch, comprise the material cooling bath that is placed on the frame and be lifted on rotation paddle in the cooling bath, wherein: cooling bath is sandwich and is provided with the circulating cooling liquid import and export that the cooling bath bottom offers feed opening; Be provided with the helical form cooling tube in cooling bath, the circulating cooling liquid of cooling tube is imported and exported, the circulating cooling liquid of cooling bath is imported and exported and is connected with inlet with the liquid outlet of circulating coolant pump respectively.
In the utility model, the cooling bath vallecular cavity is cylindrical structural, and its cavity is the stainless steel of acid and alkali-resistance or polytetrafluoroethylene (PTFE), polyethylene material; The rotation paddle is lifted in the cooling bath by the cantilever that is connected on the frame; Described rotation paddle is by motor-driven or manually rotation drives.
The helical form cooling tube is installed on the cooling cell wall by draw-in groove, can be easy to dismounting, is convenient to the cleaning of device, and this cooling tube size is according to the size customization of cooling bath.
Rotating spoon and low temperature circulation coolant pump model are determined according to the laboratory needs.The effect of stirring mainly contains two: the first, and make temperature of charge even, improve the heat exchanger effectiveness of material and cooling fluid; The second, the whirlpool that forms during stirring accelerates the natural cooling velocity of material.The circulating cooling liquid medium is ethanol.
Advantage of the present utility model is: the cooling effectiveness height, equipment is simple, easy to use, cost is low, economic environmental protection, practicality are good.Realize cooling bath cavity circulating cooling liquid and material heat exchange, cooling tube cooling fluid and material heat exchange and stirred the triple three-dimensional cooling effect that accelerates the heat transfer heat radiation by this device, greatly improved cooling velocity.
